The standard exhaust system are a 2.5" so a 3" center section will no will not fit.

Just out of interest, why would you keep the standard DP but want to change to a 3" after the cat? Even if you could do this (ie have a 2.5" flange at the DP) you would gain very little as you are only losing one cat but keeping the main restriction (cat) in the stock DP.
